Topic: [SOLVED] Solo USB microphone problem (Read 8425 times)

Here is a fix that worked for me when my 8.10 system went down with Sandy and as I rebuilt it I decided to fix all those little things that irritated me along the way:

This problem is apparently a bug that has been documented with other ubuntu users of that era and was successfully fixed by upgrading alsa to later versions. I decided to upgrade to the most recent alsa version after my tv, video etc were all working and I found that when I downgraded, as suggested above, the phone worked but the tv, video sound did not and I didn't want to jump into the morass of an earlier alsa to figure it out.

root@dcerouter:~# cat /proc/asound/versionAdvanced Linux Sound Architecture Driver Version 1.0.17.(the previous version which you just removed was 1.0.23)

so rather than mess around with the old driver lets dive in and try and install the latest alsa driver and see if that improves things:-----------------------------Make a directory where you are going to store things initially:

sudo mkdir -p ~/downloads/alsa---------------------------------Get all the files you will need to build alsa:

apt-get -y install build-essential libncursesw5-dev get text xmlto

sudo apt-get -y install linux-headers-`uname -r`---------------------------------------------Switch into the directory you made and start downloading the alsa files:cd ~/downloads/alsa
